The point being that there’s a huge difference between a nuclear bomb and a dirty bomb.

And according to that good old E equals MC squared there’s a vast amount of energy coming out of it. Plus all sorts of nasty particles and radioactive isotopes. This would be very bad.

A dirty bomb is something else entirely. It’s a normal explosion. You could do it with fertiliser and derv, as the IRA used to. Or any other explosive that you can find. Then add something radioactive. Say, cobalt 60 (a radioactive isotope of cobalt) from a cancer treatment or food irradiation machine. Or americium from a fire alarm. Someone actually plotted to do that second one not realising the next thing I’m about to tell you. This would not be a very bad thing. In fact, we’d pretty much not notice the radioactive part of it. Oh, there’d be a few numpties who panicked for sure, but the actual effect of a dirty bomb going off would be, over and above the bang, around and about zero.

Because radiation is really only a problem if it is concentrated. And the whole point of putting
